Health officials are currently engaged in an urgent tracing operation to locate dozens of passengers who disembarked from the MV Hondius, a Dutch cruise ship that has become the center of a hantavirus outbreak. The vessel, which departed from southern Argentina last month, has seen multiple fatalities and several confirmed infections, prompting an international effort to monitor those who may have been exposed to the virus during the voyage.

Discrepancies in passenger counts have complicated the search, with reports indicating that between 29 and 40 individuals left the ship during a stop at the remote South Atlantic island of St Helena on April 24. Among those who disembarked was a 69-year-old Dutch woman who later died in South Africa. Her husband had previously passed away while on board the ship; however, his death has not been officially linked to the hantavirus. In total, three people associated with the cruise have died, and several others have required emergency medical evacuation, including British, German, and Dutch nationals.

International health authorities have confirmed five cases of hantavirus linked to the vessel. Investigations suggest the initial infections likely occurred during a bird-watching excursion in South America, where travelers visited areas known to host the rodent species that carry the virus. While the public health risk is currently categorized as low, the potential for further cases remains due to the disease’s incubation period, which can last up to six weeks. Health agencies in various countries, including Singapore, the United States, and the Netherlands, are actively monitoring passengers who returned home, with some individuals currently in isolation as a precautionary measure.

Oceanwide Expeditions, the operator of the MV Hondius, maintains that it is in constant contact with global authorities to manage screening and quarantine procedures. The ship is currently en route to the Canary Islands, where further medical assessments are expected upon arrival. Meanwhile, local authorities on St Helena and its neighboring territories have implemented contact tracing protocols to safeguard their small, isolated populations from potential transmission.
